在swift中添加沒有標籤欄控制器的標籤欄

Question

我需要在標籤欄控制器中添加標籤欄，因爲在我的prepareForSegue函數中，我將數據傳遞給包含標籤欄的視圖。

我添加了對象庫中的標籤欄及其項目，並在我的視圖類中添加了UITabBarDelegate。 我的代碼是這樣的：

class SchedaCompletaVC: UIViewController, UITabBarDelegate { 

var event:Event! // data passing from prepareforsegue 

@IBOutlet var mainTabBar:UITabBar! 
var descrizioneTab:UIViewController! //if i click on first tab, so my default view 
var mappaTab:UIViewController! // second tab 

override func viewDidLoad() { 
    super.viewDidLoad() 
    println("event \(event.eventId)") 

    // Do any additional setup after loading the view. 
} 

func tabBar(tabBar: UITabBar, didSelectItem item: UITabBarItem!) { 
    switch (item.tag) { 
    case 1: 
     self.view.insertSubview(descrizioneTab.view.belowSubview(mainTabBar)) //here I had error 
     break; 
    case 2: 
     //if second tab is selected 
     break; 
    default: 
     break; 
    } 
} 

我得到這個代碼從tutorial whitch是Objective-C中，我試圖將其轉換成快捷。

我的代碼不起作用，我不知道該怎麼辦？

請幫忙。謝謝！

更新： 我的故事板是這樣的：

我只有一個Objective-C的解決方案。它工作正常;也許你可以把它轉換成Swift。

ViewController.h文件代碼

  #import <UIKit/UIKit.h> 

     @interface ViewController : UIViewController<UITabBarDelegate> 
     @property (weak, nonatomic) IBOutlet UITabBar *mainTabBar; 

     @end 

ViewController.m文件

#import "ViewController.h" 
      #import "MyFirstTabViewController.h" 
      #import "MySecondTabViewController.h" 
      @interface ViewController() 
      { 
       UIViewController *viewController1; 
       UIViewController *viewController2; 
      } 

      @end 

      @implementation ViewController 

      - (void)viewDidLoad 
      { 
       [super viewDidLoad]; 
       // Do any additional setup after loading the view, typically from a nib. 
       self.mainTabBar.delegate=self; 
      } 


      - (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item { 



       switch (item.tag) { 
        case 1: 
         if (viewController1 == nil) { 
          viewController1 = 
          [[UIStoryboard storyboardWithName:@"Main" 
                 bundle:NULL] instantiateViewControllerWithIdentifier:@"First"]; 

         } 
         [self.view insertSubview:viewController1.view belowSubview:self.mainTabBar]; 

         break; 
        case 2: 
         if (viewController2 == nil) { 
          viewController2 = 
          [[UIStoryboard storyboardWithName:@"Main" 
                 bundle:NULL] instantiateViewControllerWithIdentifier:@"Second"]; 

         } 
         [self.view insertSubview:viewController2.view belowSubview:self.mainTabBar]; 

         break; 
        default: 
         break; 
       } 
      } 


      - (void)didReceiveMemoryWarning 
      { 
       [super didReceiveMemoryWarning]; 
       // Dispose of any resources that can be recreated. 
      } 

      @end 

不要忘記。

1）標籤對標籤欄的項目（第一個選項卡項標記是1，對於第二個選項卡的項目，標籤是2）

2）的ViewController（第一和第二故事板標識符，分別地）

Answer 2

這裏是SWIFT版本： -

import UIKit 

class ViewController: UIViewController, UITabBarDelegate { 

    @IBOutlet weak var mainTabBar: UITabBar! 

    var viewController1: UIViewController? 
    var viewController2: UIViewController? 


    override func viewDidLoad() { 
     super.viewDidLoad() 
     // Do any additional setup after loading the view, typically from a nib. 
    } 

    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
     // Dispose of any resources that can be recreated. 
    } 

    func tabBar(tabBar: UITabBar, didSelectItem item: UITabBarItem!) { 

     switch item.tag { 

     case 1: 
      if viewController1 == nil { 

       var storyboard = UIStoryboard(name: "Main", bundle: nil) 
       viewController1 = storyboard.instantiateViewControllerWithIdentifier("ViewController1") as! ViewController1 
     } 
      self.view.insertSubview(viewController1!.view!, belowSubview: self.mainTabBar) 
      break 


     case 2: 
      if viewController2 == nil { 

       var storyboard = UIStoryboard(name: "Main", bundle: nil) 
       viewController2 = storyboard.instantiateViewControllerWithIdentifier("ViewController2") as! ViewController2 
     } 
      self.view.insertSubview(viewController2!.view!, belowSubview: self.mainTabBar) 
      break 

     default: 
      break 

     } 


    } 


} 

那麼你應該單擊它UITabBarItem & Ctrl拖動到viewcontroller並點擊委託。

標籤的標籤欄項目（第一個選項卡項目標記爲1，對於第二個選項卡項目，標籤是2）

故事板標識符視圖控制器（ViewController1和ViewController2，分別）
